I have a Pfaff 2134 and the needle down works just as you said in the first sentence. When in the needle down position just tap the foot control to raise the needle. Although after that tap to raise the needle, it continues with the "needle down" function when you begin sewing again if you don't change the button. Tapping the foot control sure does not raise the presser foot on mine, nor would I want it to. Good luck service number, I hope you can get some help with this. Please let us know.
